A little about a lot ...

Specialisation can unearth insight and deep understanding - but specialisation to the exclusion of everything else can lead to lost opportunity and an inability to adapt. Besides, when we specialise in something - extra effort invested in that particular area will probably only yield incremental returns - whereas investing our effort in areas we know littler to nothing about, will likely yield a huge return for time invested. Know a little about a lot ... be a Jack of all Trades, if you will. Be a well-rounded, adaptable and knowledge-hungry being. After all, your time is being spent -= whether you like it or not.
